DROP
EXTENSION

Name

Synopsis

Description

DROP EXTENSION removes extensions
from the database. Dropping an extension causes its component
objects to be dropped as well.

You must own the extension to use DROP
EXTENSION.

Parameters

IF EXISTS

Do not throw an error if the extension does not exist. A
notice is issued in this case.

name

The name of an installed extension.

CASCADE

Automatically drop objects that depend on the extension,
and in turn all objects that depend on those objects (see
Section 5.13).

RESTRICT

Refuse to drop the extension if any objects depend on it
(other than its own member objects and other extensions
listed in the same DROP command).
This is the default.

Examples

To remove the extension hstore from
the current database:

DROP EXTENSION hstore;

This command will fail if any of hstore's objects are in use in the database, for
example if any tables have columns of the hstore type. Add the CASCADE
option to forcibly remove those dependent objects as well.

Compatibility

DROP EXTENSION is a PostgreSQL extension.
